Microsoft Edge Developer

Hi, are you a web developer or designer?

“No, I just want to share feedback on Microsoft Edge.”

Please use the Feedback Hub (requires Windows 10) to submit your feedback in the Microsoft Edge category. This site is for web developer and designer feedback only. Other feedback will be closed without action.

“Yes, I’m a web developer or designer with feedback for the Microsoft Edge platform.”

Great! This site is where the Microsoft Edge team collects feature requests from the web developer and designer community in the categories listed to the right. For bugs on existing features, please log an issue on the Issue Tracker.

Your feedback will help us with planning and to better understand how web developers and designers are using the platform. Top standards-based feature requests will also be copied over to status.microsoftedge.com, where you can track its development status.

For the most actionable feedback, please search and up vote for existing suggestions before submitting a new suggestion, and create a separate suggestion per idea. Note that off topic or inappropriate suggestions may be moderated. The Microsoft Edge team will use suggestions as an important input, but there are several additional factors that inform the final roadmap.

A note from our lawyers: Please do not send any novel or patentable ideas, copyrighted materials, samples or demos which you do not want to grant a license to Microsoft. See the Terms of Service for more information.

How can we improve the Microsoft Edge developer experience?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

    • Native messaging!

      Please implement Native messaging mechanism! Internet Banking users are used to sign their contracts via a smart card (which uses WinCrypt API). Nowadays, after deprecation of applets, there is no other way to access Windows API and use a smart card in order to make a trusted digital signature.

              • CSS Intrinsic Sizing

                Extends the CSS sizing properties with keywords that represent content-based "intrinsic" sizes and context-based "extrinsic" sizes, allowing CSS to more easily describe boxes that fit their content or fit into a particular layout context.

                    • Support CSS Motion Path Module

                      Since SMIL will be deprecated in Blink and there is no intent to implement in MS Edge, we need to fill in the gaps and provide alternative ways to do with CSS what we could do in SMIL.

                      The CSS Motion Path spec is now a Level 1 module and is in W3C Working Draft status:: http://www.w3.org/TR/2015/WD-motion-1-20150409/

                      Using the properties defined in this specification, we will be able to animate HTML and SVG elements along arbitrary paths, using nothing but good old CSS.

                      There is a bug report open to fixes in Blink, hopefully to make it to implementation this…

                      • W3C Manifest support

                        Add support for the new W3C manifest specification for pinned apps as well as for Windows store applications.

                        The spec allows for vendor extensions which can be used for things missing in the Level 1 of the spec. A lot of things have already been planned for Level 2 so it would be great if the MS team could participate in the discussions

                        • image-rendering: pixelated

                          This declaration is used to preserve pixels when scaling up images (e.g. pixel art). IE provides this functionality via -ms-interpolation-mode: nearest-neighbor. The other browser engines also provide this functionality (see here: http://www.simevidas.com/2015/05/10/Blowing-up-pixel-art-on-the-Web.html).

                          • Implement conic gradients from CSS Image Values Level 4

                            Conic gradients [1] are useful for a number of effects on the Web that cannot be emulated in any other way (see [2]). They can be implemented in many graphics libraries today (e.g. Cairo) via mesh gradients. Please implement them.

                              • headless browser for testing

                                It would be great if IE could be started as a headless browser (like PhantomJS) for running unit tests, taking screenshots, measuring load time, etc without having a browser window pop up. Running automated tests on IE often fails because the browser either fails to start up or shut down properly. With a headless browser multiple browser instances can be run in parallel without taking up screen space.

                                    • Debug for Edge on mobile/Xbox/RaspberryPi

                                      Just like it happens for OSX/iOS, where attaching a device via USB or connecting via wifi allows to use desktop safari to inspect mobile safari and webviews on the mobile. All other browsers support this but Edge.

                                      I know weinre was recently adapted to be usable on Edge mobile too but it's hardly a complete solution for serious development, lacking support for breakpoints, CSS pseudo-element.

                                      Not to mention that I did encounter really strange behaviors of the DOM inspection panel based on when the weinre resources are loaded during JavaScript execution, something that is not acceptable to develop modern SPA…

                                      • ES6 Tail Call Optimization

                                        Besides providing better tools for JS devs, this will greatly enhance JavaScript's support for functional languages compiled to JS, like ClojureScript.

                                          Header for proactive content negotiation; just as the Accept header allowed clients to indicate what formats they prefer, Client Hints allow clients to indicate a list of device and agent specific preferences.
